Containerized vs. ground in the cold.
I am very surprised by an observation I have made regarding containerized vs. planted Washintonia palms. I still have out tree large ones in containers. They are in tubs on the south side of detached garage--they get full sun most of the day in Winter when it is clear outside. I have two others that are planted next to the house in the ground in western exposure (unprotected at this point). The one in containers are completely undamaged but I see some minor burning on a few leaves on the ones in the ground--opposite of what I would expect. Why is this? P.S. If it is a normal winter, I would eventually have to protect both--but so far, December is mild after a cold November.
